Does Time protocol expire?
Time Protocol (rfc868) uses 32-bit binary timestamp, which represents time in seconds from 0h 0m 0s UTC on January 1, 1900. After 6h 28m 16s UTC on 7 February 2036 most significant bit of this timestamp will overflow 32 bit DWORD value and will lost. The time stamp will become zero. Should Time Protocol be in use in 2036, some external means will be necessary to qualify time relative to 1900 and time relative to 2036 (and other multiples of 136 years). Most likely future versions of Advanced Time Synchronizer will still support Time Protocol after 7 February 2036.
